TIME-INDICATOR.

SPECIFICATION forming part of Letters Patent No. 649,198, dated May 8,1900.

Application filed July 5, 139th Serial N0. 722,885. (No model.)

To (LZZ whom it may concern:

Be it known that 1, WILLIAM C. EGERTON, a citizen of the United States,and a resident of New York, county of New York and State of New York,have invented certain new and useful Improvements in Time-Indicators, ofwhich the following is a specification, reference being had to theaccompanying draws ings, forming a part thereof, in which similarletters of reference indicate corresponding parts.

My invention relates to an improved and novel article of manufacture;and its object is to provide a cheap, ornamental, and convenient devicefor determiningthe time at any moment invariouspa ts of the world.Iattain this object by the device illustrated in the accompanyingdrawing-s, in which Figure 1 is a general front View of the device.Fig.2 is a side view of same. Fig. 3 is a detail view showing the methodof connecting the revolving parts. Fig. et is a view of theconnecting-pivot, and Fig. 5 shows a slight modification of index onarm.

' Similar letters refer to similar parts through= out the drawings.

In the practice of my invention I provide a dial A with markings to,representing degrees of longitude east and west of London. The markopposite London indicates 0 degrees, and moving around on the circle .toeast and west every fifteenth degree is numbered. The space between eachmark represents five degrees.

At various points around the dial A are marked different cities andlocalities of the world, each city or locality being opposite its properdegree-mark.

Ooncentrically fastened to the dial A by means of the pivot b is asecond dial B. The dial B is provided with markings b, which indicatehours, half-hours, and quarter hours. The dial B is further marked withthe circular band 0, half of which is shaded and which indicates thatall places radially opposite said shaded portion are in darkness whenthe device is set for a reading.

A small lug b is formed upon the dial B and is employed as a key forrevolving said dial B. Pivotally fastened at the center is an indicatingarm or pointer D. Said arm has an index at formed upon its under side,which is employed in conjunction with the markings h to read the time atthe place desig nated by the end (1 of the pointer D.

The connecting=pin Z) is formed with a circular flange b and forms a bedfor the dial B. The parts are all fastened together, so as to revolveabout the pivot b.

The dial A is provided with the legs a and the hinged leg of, whichaitord means for standing the device in an upright position.

The device operates as follows: The dial B is set with12on line with NewYork. If it is desired to determine the time on the device at Alaska,the indicating-arm is swung around so that the point d comes in linewith Alaska, and the time that it is at Alaska when it is twelve noon atNew York would then be shown on the dial B, radially opposite the indexd on the arm D-viz., seven a. m. In the same manner the time at anylocality may be determined at any time of the day.

In the drawings I illustrate a construction for a metallic device; butit is obvious that the device may be constructed of paper or any othersuitable material. If paper is used, the arm D would necessarily have tobe fiat, and the index could be formed as shown in Fig. 5. In connectingthe parts the common eyelet-fastening would have to be employed.

The legs a and a may be omitted and the entire device be circular inshape.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The combination, in a time-indicator, em bodying a dial provided withsuitable markings representing localities, and a secondary dial Bconcentrically mounted uponsaid dial and provided with numericalmarkings representing time,0f an indicating-arm D mount= edconcentrically with said dials, indexes d and d formed upon said arm D,a rivet formed with a ledge b and adapted to hold dials and arm inposition in such a manner so that the secondary dial B does not setclirectly upon the dial A, and a lug 1) formed July, 1899. upon thesecondary dial B to afford a means ,1 r l T for revolving secondarydial, substantially] WILLIAM LGERJ'U1\' 5 as described. lVitnesses:
